10x String Insert for UST-M PP20M 10" Water Filter USTM 20 MICRONS

Effective mechanical sediment filtration

The string filter cartridge, also known as a non-woven cartridge, is one of the most commonly used solutions for mechanical water filtration. Its operation is based on retaining contaminants through the dense weave of string fibers, so the water directed further through the system is better protected against the presence of solid particles.

The USTM PP20M model is designed to capture contaminants up to 20 microns in size. This filtration level is suitable for reducing typical sediments present in water, which translates into better protection of installation components and devices that use water.

Main advantages of USTM PP20M cartridges

• trap contaminants down to 20 microns,
• feature a gradient structure that supports more precise and efficient filtration,
• are characterized by a higher fiber weave density of the strings compared with other cartridges available on the market,
• work well in in-line filters used for the whole house or apartment,
• can also be used in kitchen water filters installed under the sink,
• are recommended for protecting plumbing systems, fixtures, and household appliances,
• have PZH certification,
• were manufactured in Poland.

Gradient structure and higher filtration efficiency

One of the important features of this cartridge is its gradient structure. This means a change in the density and type of fibers along the length of the cartridge, which allows different types of contaminants to be retained more effectively. In practice, fibers with varying density can efficiently capture particles of different sizes, which helps improve the quality of purified water.

This solution is especially beneficial where the water filter operates regularly and is meant to protect subsequent treatment stages. The cartridge can serve as a good pre-treatment stage before more precise purification, also in systems such as a reverse osmosis filter or reverse osmosis.

Longer service life and system protection

Thanks to its gradient design, string cartridges can operate longer before clogging. This translates into a longer service life, less frequent replacement, and lower maintenance costs for the water filtration system.

In everyday use, this means not only convenience but also real support for the entire installation. Mechanical removal of sediment helps reduce the buildup of contaminants in fixtures, household appliances, and filter housings, which is why the cartridge is eagerly chosen for both domestic and kitchen applications.

Application
